The embodiments of this utility model will now be described based on its overall structure.

[0031] Figure 1 and Figure 2 This is a schematic diagram of the structure of the first sorting mechanism provided by this utility model. Figure 3 This is a schematic diagram of the flow guiding mechanism provided by this utility model. Figure 4 This is a structural schematic diagram of the lifting assembly provided by this utility model. Figure 5 and Figure 6 This is a schematic diagram of the structure of the second sorting mechanism provided by this utility model. (See attached diagram.) Figures 1-6 The litchi sorting device includes: a first sorting mechanism 2, a flow guiding mechanism 3, and a second sorting mechanism 4.

[0032] See Figure 1 and Figure 2 The first sorting mechanism 2 includes a plurality of first sorting belts 21, a first idler support assembly 22, and a second idler support assembly 23. The first idler support assembly 22 is connected to the first end of the first mounting platform 24, and the second idler support assembly 23 is connected to the second end of the first mounting platform 24. The first sorting belts 21 are connected to the first idler support assembly 22 and the second idler support assembly 23. The plurality of first sorting belts 21 radiate from the middle position of the first end of the first mounting platform 24 to the second end of the first mounting platform 24, and the first sorting belts 21 surround the first mounting platform 24.

[0033] In this process, the distance between multiple first sorting belts 21 gradually increases from the first end of the first mounting platform 24 to the second end of the first mounting platform 24, and gaps are formed between the multiple first sorting belts 21 for lychees to pass through. The first sorting belts 21 can move on the idler roller support assembly. When lychees pass through the first sorting belts 21, the movement of the first sorting belts 21 allows lychees of different sizes to fall through the gaps between the first sorting belts 21, thereby completing the initial screening of lychees.

[0034] See Figure 3 and Figure 4 The flow guiding mechanism 3 includes a first flow guiding channel 31, a second flow guiding channel 32, a third flow guiding channel 33, and a lifting assembly 34. The lifting assembly 34 is connected to the first mounting platform 24. The first flow guiding channel 31, the second flow guiding channel 32, and the third flow guiding channel 33 are connected to the lifting assembly 34, and the first flow guiding channel 31, the second flow guiding channel 32, and the third flow guiding channel 33 are located below the first sorting belt 21.

[0035] The first guide channel 31, the second guide channel 32, and the third guide channel 33 are used to divert lychees of different sizes. The lychees in the second guide channel 32 are larger than those in the first guide channel 31, and the lychees in the third guide channel 33 are larger than those in the second guide channel 32.

[0036] To prevent lychees from accumulating in the flow channels, lifting components 34 are installed at the bottom of the first flow channel 31, the second flow channel 32, and the third flow channel 33. These lifting components 34 allow the flow channels to continuously rise and fall. When the flow channels descend, they come into contact with the first mounting platform 24, which exerts a significant upward impact force. This impact causes the flow channels to vibrate. Therefore, by utilizing this impact to vibrate the flow channels during descent, lychee accumulation within the channels is prevented.

[0037] In this system, because the sorting belt of the first sorting mechanism 2 is set in a radial configuration, the lychees exiting from the first guide channel 31, the second guide channel 32, and the third guide channel 33 will have three different sizes. However, it is inevitable that some lychees of different sizes will exist within each size. This still presents a drawback for selling lychees at different price points. Therefore, a second sorting mechanism is set up to perform secondary sorting of the lychees exiting from the first guide channel 31, the second guide channel 32, and the third guide channel 33. (See reference...) Figure 5 and Figure 6 The second sorting mechanism 4 includes a plurality of second sorting belts 41, a third idler support assembly 42, and a fourth idler support assembly 43. The third idler support assembly 42 is connected to the first end of the second mounting platform 44, and the fourth idler support assembly 43 is connected to the second end of the second mounting platform 44. The second sorting belts 41 are connected to the third idler support assembly 42 and the fourth idler support assembly 43. The distance between two adjacent second sorting belts 41 is equal, and the second sorting belts 41 surround the second mounting platform 44. The second sorting belts 41 are located below the first guide trough 31, the second guide trough 32, and the third guide trough 33.

[0038] The distance between the second sorting belts 41 below the first guide trough 31 is set according to the size of the lychees flowing out of the first guide trough 31, and the distance between two adjacent second sorting belts 41 is the same. The distance between the second sorting belts 41 below the second guide trough 32 is set according to the size of the lychees flowing out of the second guide trough 32, and the distance between two adjacent second sorting belts 41 is the same. The distance between the second sorting belts 41 below the third guide trough 33 is set according to the size of the lychees flowing out of the third guide trough 33, and the distance between two adjacent second sorting belts 41 is the same.

[0039] The lychees emerging from the first guide channel 31, the second guide channel 32, and the third guide channel 33 will be of three sizes. These three sizes are relatively stable in size. After passing through the second sorting belt 41, as the second sorting belt 41 moves, because the distance between the two sorting belts is equal, lychees of the same size will fall between the two belts, while lychees of different sizes will remain on the second sorting belt 41 and be transported to the end for collection. The lychees falling between the two sorting belts 41 are generally of uniform size, which better meets market requirements for lychee pricing.

[0040] See Figure 3 and Figure 4 The first guide channel 31, the second guide channel 32 and the third guide channel 33 are respectively connected to the diverter plate 35. The diverter plate 35 includes a first diverter plate 351 and a second diverter plate 352, and the first diverter plate 351 and the second diverter plate 352 are connected in a triangle.

The movable plate 47 is provided with a first fruit frame 11. The first fruit frame 11 is located below the second sorting belt 41. The second end of the second placement platform 44 is provided with a second fruit frame 12. The second fruit frame 12 is located below the second sorting belt 41.

[0042] The roller can move within the guide rail 460, allowing the moving plate 47 to move below the second sorting belt 41, thereby enabling the first fruit frame 11 to move out from the end of the second sorting mechanism 2, facilitating the collection of lychees within the first fruit frame 11.

[0043] There are two guide rails 460, and multiple rollers connected to the moving plate 47. A pad is also provided below the second fruit frame 12, which can shorten the distance between the second fruit frame 12 and the second sorting belt 41.

[0049] Two partitions 28 are connected to the first placement platform 24, and the first sorting belt 21 is disposed between the two partitions 28.

[0050] Two partitions 28 are connected to the first placement platform 24, and the first sorting belt 21 is disposed between the two partitions 28. The partitions 28 can partially cover the top of the first guide channel 31, the second guide channel 32, and the third guide channel 33, so that only the area where the first sorting belt 21 is disposed exists on the top of the first guide channel 31, the second guide channel 32, and the third guide channel 33, and a channel for lychees to pass through is formed between the two partitions 28.

[0051] See Figure 3 and Figure 4 The first guide channel 31, the second guide channel 32 and the third guide channel 33 each include two guide channel bodies 36, and the two guide channel bodies 36 are symmetrically connected to the lifting assembly 34.
